The solution to the equation 4(z−2)=20 is z=7.
To solve the equation 4(z−2)=20 for z, you can follow these steps:
Distribute the 4 on the left side of the equation:
4z−8=20
Add 8 to both sides of the equation to isolate the term with z:
4z−8+8=20+8
4z=28
Divide both sides by 4 to solve for z:
4z /4 = 28/4
z=7
So, the solution to the equation 4(z−2)=20 is z=7.
